Intake Manifold Inspection
INSPECT INTAKE MANIFOLD
INSPECT VACUUM SWITCHING VALVE
Intake Manifold -- Inspection |
1. INSPECT INTAKE MANIFOLD |
- NOTICE:
- Do not adjust the adjusting screw or 2 actuator installation bolts.
Check the operation of the swirl control valve.
Check that the valve is fully opened under normal conditions.
Connect a vacuum pump to the control valve. Check that the valve is fully closed when a negative pressure of 66.7 kPa (500 mmHg, 19 in.Hg) is applied.
Leave it for 1 minute and check that the vacuum pump needle does not move. If the result is not as specified, replace the intake manifold.
